Post by wchin on Passing EtheNetIP adapter device into a Function Block to access it's IO ^{CODESYS Forge talk (Post)}
We are creating helper function blocks for our VFD(EtherNetIP). How should I set it up so that I can pass the device into and out of the Function Block so that ideally I can access the IO of the device by devicename.channelname. So something like for example we have a VFD with a start bit that is in the ControlWord channel and a SetVelocity that is a channel. And we want to create a Function Block called StartVFD. So I declare something like: FUNCTION_BLOCK StartVFD VAR_IN_OUT device: ioDrvEthernetIP.RemoteAdapter; END_VAR VAR_INPUT velocity : REAL; So in the code it would look something like device.SetVelocity := velocity; device.ControlWord.6 := True; We have a pretty basic eds file for our VFD and can update it if necessary. Thanks in advance.

Post by transmin01 on EL6751 Canopen_Manager issue ^{CODESYS Forge talk (Post)}
Hi, I have a Beckhoff EL6751 EtherCAT / CANopen gateway which fails on the Canbus when the CANopen_Manager is added. Currently no devices are connected to the EL6751. If I add a device, I get the same issue. If I add a device and connect the bus, I get the same issue. Is there something I am doing wrong? Regards Trevor

Post by laruso on Runtime device Enable/Disable procedure ^{CODESYS Forge talk (Post)}
I implemented the parts from the CAA Device Diagnosis Example.project and could use it for switching on and off, the CAN devices that were located under the CANbus and CANopen_Manager. But i can't do the same with I2C_master_test_version or devices below this one. In the example project there is only the EtherCAT Master, CANbus and CANopen_Manager, and Ethernet with devices below.

After many tests i see that problem comes when serial communication established for modbus rtu. If the slave device not connected we don't see the exception. If the slave device connected at serial port then we have exception about 1 hour after startup and every 10 or 15 minutes. Any suggestion?

I have working EtherCAT since it can be scanned for slaves, but then I'm stuck getting the information that the device isn't found in the repo. As far as I can see both revisions does however exist in the device repo. Component added in the Configfile. Anyone with some similar experiences?

I initially created a SoftMotion axis for my EtherCAT CoE drive. I wanted to change it to use SoftMotionLight so I deleted the SM node, which left an <empty> node. I created the SML device, but the <empty> node remains. How can I remove that from the tree? </empty></empty>

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

I have a video demonstrating the procedure to install the runtime on a linux device. https://youtu.be/rj0dOhgnGjs?si=OJoA-kgc1saxIweR This demonstration shows how to install the runtime on a X86 based controller, it should be the same for an ARM based device, but you'll need to install the add-in for Codesys control for Linux ARM SL (or the 64 bit add-in.)

Post by masmith1553 on SDO generation ^{CODESYS Forge talk (Post)}
If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

Hey guys, I'm currently developing a Codesys application for an offline Linux device. I can easily set up the license for ONE device using my Windows PC, but what happens if I need to produce a thousand devices? Is there any method to automate license insertion? I have already generated a dpkg installer for deploying the Linux control application to multiple targets. Thanks,

it works pretty well on codesys-version using device-tree and channels. heres the twist: each uid should be represented as a device, which in your case, it isn't. on the other hand, you found a solution which already works fine. Happy Modbus'ing
